Description

[Detailed Description of the Invention] The present invention is an improvement of an automobile brake cooling system.

Generally, in an automobile, since wind does not reach the inside of a wheel on which a disc brake is disposed, for example, it is necessary to separately provide a brake cooling device.

Such a brake cooling system, for example, as described in Utility Model Application Publication No. 14642/1983, is provided with a duct directed toward the brake, and a drive fan is provided within the duct, thereby providing forced cooling to the brake. There is something that allows the wind to flow.

However, with this structure, there is a problem in that there is not enough space to arrange the duct, and a driving fan must be provided separately, which increases the cost.

By the way, in general, rainwater, mud, etc. that adhere to the wheels
In order to protect the panels located above the wheels, such as the wheel apron and front fender panel, from flying pebbles, etc., a mud guard is provided to cover the top of the wheels. In automobiles equipped with a washer tank, headlamp, etc. in the space between the fender panel and the wheel apron, the front end of the muzzle guard is extended toward the front of the vehicle to protect them from flying stones, mud (water), etc. It is used as a protector.

In view of this, the present invention was developed by focusing on the fact that there is a space between the fender panel and the wheel apron. The cooling air introduced and guided can cool the brake part (e.g. disc brake) located on the inside of the front wheel, and the air duct forms the front end of the muzzle guard, giving it the function of a protector. The main object of this invention is to provide an automobile brake cooling device that can be manufactured at low cost by omitting a part of the mud guard.

In order to achieve the above object, the present invention is located in front of the front wheels and in the space between the inside of the vehicle body of the front fender panel and the outside of the vehicle body of the wheel apron, and the front end is located in the air dam skirt. The present invention is characterized in that an air duct is provided whose rear end is open to the front side of the front wheel, and the front end of a mudguard that covers the upper part of the front wheel is joined to the upper surface of the air duct.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 4, it is located at the front of the automobile 1, ahead of the front wheels 6, and on the inside of the vehicle body of the front fender panel 2 and the wheel apron 3.
An air duct 4 is arranged and supported in the space between the outer side of the vehicle body and the outer side of the vehicle body. The front end of the air duct 4 opens at the air dam skirt 5, while the rear end opens at the front part of the front wheel 6, so that when the vehicle is running, the air duct 4 passes through the brake part (not shown) on the inside of the front wheel 6. ) is supplied with air and cooled.

The air duct 4 is basically a closed cross-sectional shape formed by joining a hat-shaped upper member 7 and a lower member 8. That is, the upper portion 7 is composed of a base portion 7a having a square cross section and flange portions 7b, 7c extending horizontally from the side edges of the base portion 7a, while the lower member 8 is composed of a base portion 8a having a square cross section and flange portions 7b, 7c extending horizontally from the side edges of the base portion 7a.
A flange portion 8b extending horizontally inward from the inner edge of the
The base 8a has an extension 8c extending horizontally outward from its outer edge, and a vertical portion 8d extending vertically downward from the side edge of the extension 8c. The flange 8b and the extension 8c of the lower member 8 are connected to the upper member 7.
The flanges 7b, 7c of the first and second air passages 7a, 7b are fixedly joined to each other, thereby forming an air passage A having a rectangular cross section.

The base portion 8a of the member 8 is connected and fixed at its inward vertical portion to a substantially horizontal undercover 10 via a connecting bracket 9 having a substantially L-shaped cross section, and at the same time, its upper horizontal portion is connected to a mounting bracket 11.
It is attached and fixed to a fender stay 12 that connects the fender panel 2 and the wheel apron 3 via.

The undercover 10 includes an upper horizontal portion 13a,
An intermediate vertical portion 13b and a lower horizontal portion 13c are attached and fixed to the lower horizontal portion 13c of the support bracket 13, which is successively arranged. A wheel apron 3 is provided at the intermediate vertical portion 13b of the support bracket 13.
Since the vertical portion 3a of the undercover 10 and the wheel apron 3 are connected and fixed, the undercover 10 and the wheel apron 3 are connected via the support bracket 13.

Moreover, in the vertical part 3a of the wheel apron 3,
A front frame 14 having a hat-shaped cross section is joined and fixed to form a closed cross-sectional structure extending in the longitudinal direction of the vehicle body.

The fender stay 12 has one end directly joined and fixed to the vertical part 2a of the fender panel 2, and the other end to the upper horizontal part 13 of the support bracket 13.
a and is indirectly connected to the wheel apron 3.

Further, the front end of a mudguard 16 that covers the upper part of the front wheel 6 is bonded and fixed to the rear end of the upper member 7 constituting the upper surface of the air duct 4, thereby forming a part of the mudguard 16.

With the above configuration, when the automobile 1 is running, air is introduced from the front end of the air duct 4 that opens in the air dam skirt 5, and the introduced air passes through the inside of the air duct 4 and reaches the front portion of the front wheel 6 that opens. As a result, the brake section (not shown) located inside the front wheel 6 is actively cooled, and it is also effective in lowering the atmospheric temperature in the engine room.

In addition, since a washer tank (not shown) is located above the air duct 4, the air duct 4
functions as a protector for the water tank,
For example, it functions as a protector against flying stones.

In the above embodiment, the fender stay 12 is used to connect the fender panel 2 and the wheel apron 3, but as shown in FIG.
The fender stay can also be omitted by bonding and fixing the extended joint portion 8e extending outward from the outer edge of the base portion 8a of the lower member 8 to the vertical portion 2a of the fender panel 2. In that case, the bracket 15 connecting the undercover 10 to the wheel apron 3 has an L-shaped cross section.

As described above, the present device utilizes the space between the fender panel and the wheel apron to position and support the air duct, so that the brake section located on the inside of the front wheel can be cooled without causing problems with placement space.In addition, because the air duct forms the front end of the false eye guard, part of the false eye guard can be omitted and it can be manufactured inexpensively, which has excellent practical effects.
